charting missing data (empty cells bug)

[Kazim Mammadhuseyn]

Hi
I'm trying to chart data with some missing points. I read posts on this forum on this topic and checked with my settings but they seem to be OK. Still, my empty cells are plotted as zeros. Only one (!) cell out of 5 is not plotted(and I failed to figure out how that one was different from the rest).

Here are the current settings:
- Excel version is French.
- Cells are not hidden, but protected.
- They are customized at "empty cell" format (;;
- Empty cells are set to be plotted as gaps.

Your help would be very much appreciated.

Oh, I almost forgot it: I'm using the 2007 version

Hi,

Charts take a cell with content that is not numeric as being text and as
such treat it as zero.
If your cell contains a formula you need to set the resulting unused value
using the NA()
So your formula construct will be along the lines of if not a valid value
use NA()

IF(<test> , <value> . NA() )

Note that regardless of the setting for how to chart empty cells the use of
NA() will only suppress the data marker.
If you have a line and require a break within it you will need to remove the
formula from the cell.

Cheers
Andy
